Problems solved by technology

Conversely, in order to maintain the overall power of the motor vehicle's electric drive system, the traction battery must be replaced with a new traction battery, which can be very expensive depending on the cost of the particular traction battery
In the case of conventional lithium-ion traction batteries, the cost of new traction batteries is very high for vehicle owners

Embodiment Construction

[0034] In the different figures, identical components are in each case indicated by the same reference numerals, so that these components are usually also described only once.

[0035] figure 1 A schematic diagram of an exemplary embodiment of an electrically propellable motor vehicle 1 according to the invention is shown.

[0036] The motor vehicle 1 has at least one electric traction motor 2 which can be used for recuperation in some operating situations and also as a generator. The electric traction motor 2 can be connected on the input side of an inverter not shown or in the circuit of a DC / DC converter not shown. The electric drive and the generator can be provided as mutually separate elements.

[0037] The motor vehicle 1 additionally has a battery system 3 connected to the electric traction motor 2 for supplying the electric traction motor 2 with electrical energy. The battery system 3 has a battery electronics package 4 which transmits the battery voltage to the el...

Abstract

The invention relates to a battery system (3) for an electrically drivable motor vehicle (1). The battery system (3) includes at least one set of battery electronics (4) that delivers a battery voltage, and at least one rechargeable traction battery (5) connected to an input of the set of battery electronics (4). In order to enable the traction battery (5) to be used throughout its useful life without harming the operation of the motor vehicle (1), the battery system (3) has at least one auxiliary traction battery (6), the auxiliary traction battery (6) is connected with the traction battery (5) in parallel or in series, or connected to the other input of the set of battery electronics (4).

Description

technical field [0001] The invention relates to a battery system for an electrically propellable motor vehicle, the battery system having at least one battery electronics pack, which supplies a battery voltage, and at least one rechargeable traction battery, to which the traction battery is connected. Input to the battery electronics pack. Furthermore, the invention relates to an electrically drivable motor vehicle having at least one electric traction motor and at least one battery system connected to the electric traction motor for supplying the electric traction motor with electrical energy. Background technique [0002] Electrically driveable motor vehicles, such as electric vehicles and hybrid electric vehicles, each have a traction battery via which an electric drive of the motor vehicle is supplied with electrical energy when the motor vehicle is in electric drive mode. [0003] During charging and discharging, traction batteries are subjected to powerful transition ...
